The CLUSTER SETSLOT command is an important piece used by Redis Cluster in order to migrate all the keys contained in one hash slot from one node to another

Redis Cluster uses a hash slot system to distribute data among the nodes When a new key is created, Redis applies a CRC16 데이터 분산과 Key 관리 · Redis는 16384개의 hash slot으로 key 공간을 나누어 관리 · 각 키는 CRC16 해싱 후 16384로 modulo 연산을 해 각 hash slot에
